I just recently listened to an episode of the Beer Smith podcast where Chris White and John Blichmann discussed fermenting under pressure. They did an experiment fermenting four identical beers (Munich Helles) under different conditions:
The first beer was fermented at lager temps at ambient pressure. The second was fermented at 68'F at ambient pressure. The third was fermented at 68'F at 15 psi, and the last was fermented at 68'F at 30 psi.
They used quantitative analysis (gas chromatography) to determine the amount of esters in each beer. The elevated pressure beers had less esters than even the lager fermented beer. While they claim that the lager fermented beer was identifiable by its higher level of sulfur compounds, I feel like this is a perfectly viable way to make lager styles without a temp control chamber.
Has anyone tried fermenting "Lagers" at room temp under pressure? Seems like a good way to make them quickly without refrigeration.
